Glock 32 2,000-Round Wrapup

So, here's the Gen 3 Glock 32 after firing two thousand rounds of assorted ammunition without any cleaning or lubrication after an initial application of Lucas Oil to the factory recommended lubrication points...

You've got your typical discoloration around the muzzle end. Most of this was done a hundred rounds at a time, pre-loading the three magazines I have, going into the range, shooting up that initial 39 rounds, and then again & et cetera until the 300 rounds were gone. Of note is how the White Sound Defense guide rod protrudes from the muzzle end.

 Pretty grody on the inside.

Note the schmutz collected on the front rails. Part of the reason guns like this are less sensitive to dirt or lack of lubrication is that they just have those little metal nubbins keeping the slide flying in loose formation with the frame, rather than conventional frame rails.

The brass smear on the feed rail is notable as is the sheer amount of cack around the firing pin safety.

In the first three hundred rounds, the pistol experienced three failures to go completely into battery and three failures to feed, and then one more of each around the seven hundred and fifty round mark. It was at this point that I replaced the magazine springs with 11-coil springs from full-size Glock mags, in order to ensure that the next round was lifted into place fast enough to be picked up by the slide (despite the higher slide velocities, Glock 32 magazines use the same springs as 19 mags.)

I also replaced the factory 18# recoil spring with a CrSi flat wire IMSI 20# unit. Unfortunately, this meant having to use an aftermarket guide rod, something of which I'm not generally a fan.

Sure enough, the rear cap on the three piece Lone Wolf guide rod began unscrewing around the 1,300 round mark and the rod itself actually fell out of the gun, which I noticed because the gun failed to go fully into battery at round number 1,503. I knocked the slide off the gun with a rubber mallet, reassembled the guide rod, and fired off a couple magazines, experiencing a failure to feed with defective round of Remington ammunition. (During this test, I fired a total of 1,000 rounds of Remington FMJ .357SIG, two 500-round cases. Each case had one round with the primer wadded in sideways.)

I replaced the bent Lone Wolf unit with the uncaptured White Sound Defense guide rod at the 1,629 round mark. There were no further malfunctions.

I'll note that, after the spring replacement, the only malfunction that wasn't caused by user error (me not making sure that I'd used thread-locker on the rear cap) or defective Remington ammo was the lone FTE at round #1,033.

So, that's a wrap. I think the 11-coil mag springs are the key, here, although the 20# recoil spring doesn't hurt.

Perfect Ten?

I put another hundred rounds of 10mm Auto downrange yesterday, fifty of the S&B 180gr FMJ and fifty of the Sig Sauer Elite Performance  180gr FMJ. (Indy Arms Co. has both the Sig FMJ and American Eagle in stock for range ammo.)

First up was the S&B, which claims a velocity of 1164 fps at the box flap. I fired it into that upper grouping at ten yards. It felt a little boomier than the Prvi or the Armscor, but not as stout as the Sig Sauer FMJ. I hope to get some chrono numbers for it from the range on Monday.

I then brought the target back in to five yards and fired the fifty rounds of Sig Sauer ammo weak-hand-only into that lower mess. By the time I was finished with the second mag, I was kinda regretting my decision; that stuff was a handful shooting one-handed with my left hand. Round #71 of the day (#401 of the test) was a failure-to-feed, a classic "limp wrist" malfunction caused by me holding the gun way too lightly, trying to fight an incipient flinch by focusing really hard on the trigger and forgetting to keep a good grip.

There were no other malfunctions to report.

This makes 430 rounds since the Glock 20 was cleaned or lubricated, with one failure to feed (#401). 1570 rounds to go.

Big Bang Theory...

Yesterday's  Glock 20 range outing was another fifty rounds of the Sig Sauer 180gr FMJ (which runs at a claimed 1250fps, just like their V-crown JHP offering) and fifty of Armscor 180gr FMJ, which has a velocity of 1,008 fps as measured at the ad copy.

I fired the Armscor into the upper grouping at seven yards, and then ran the target out to ten and fired the Sig ammo into the lower one. The difference in recoil between the two brands was noticeable.

All one hundred rounds cycled the weapon fine, with no malfunctions of any type to report.

Range Day

Rode with Mike Grasso out to Atlanta Conservation Club to do some chrono work and get some groups shot for a magazine article.

First thing I wanted to do was chrono some of that Prvi Partisan .357SIG to see if it was as variable as the muzzle blast & flash led me to believe...
LO: 1314
HI: 1367
AV: 1340
ES: 52.43
SD: 16.18
Well, not as bad as I feared, but still the most wildly variable of all the .357SIG FMJ I've chrono'ed out of that gun.

Then it was on to the main event: Four different 10mm loads from the Glock 20. The first up was Prvi Partisan's 170gr FMJ offering:
LO: 1020
HI: 1087
AV: 1049
ES: 66.58
SD: 19.84
So, like most commercial 10mm FMJ offerings, basically it offers another fifty to a hundred feet-per-second over a hot .40 S&W load.

On to the jacketed hollow point offerings...

I had some Hornady XTPs in both 155gr...
LO: 1290
HI: 1321
AV: 1306
ES: 30.70
SD: 11.31
...and 180gr flavors:
LO: 1109
HI: 1127
AV: 1118
ES: 17.78
SD: 6.32
That ten shot string of 180gr XTP, by the way, is the second most consistent that I've ever chrono'ed, bested only by another Hornady offering, the .45ACP 220gr +P Critical Duty out of my CCA 1911.

Last up was the 180gr V-crown JHP from Sig Sauer's new ammo division. Sig has 10mm offerings in both the P220 and 1911 platforms, and someone at Sig must be a fan of the caliber because they're loading theirs pretty spicy, the way 10mm was meant to be. I was interested to see how close the measured velocity out of a 4.6" Glock 20 barrel would come to matching the box-flap claim of 1250fps, presumably from a 5" test barrel.

I was also interested in seeing how consistent the ammo was, which is generally a pretty good indicator of QC.  The results:
LO: 1158
HI: 1215
AV: 1168
ES: 57.46
SD: 16.88
Nine rounds were all clustered within about fifteen FPS, with that one 1200fps outlier blowing the average. Still, not bad.

We shot up the remainder of the box of Prvi Partisan FMJ which, combined with the three chrono strings of JHP made a round count of eighty for the day through the Glock 20. All eighty rounds cycled normally and there were no malfunctions of any kind to report.

This makes 230 rounds since the Glock 20 was cleaned or lubricated. 1770 rounds to go.

After all the range work it was time for lunch.

A ham & brie sandwich and potato salad at Rail Epicurean Market in Westfield, washed down with some sweet tea.

AK usage yesterday: 0.
Day rating: Good.

Gratuitous Gun Pr0n #147...

Smith & Wesson Model 68, six rounds, seven yards, double-action offhand.

Overheard in the Office...

The reporter on the televisor is doing a "Man on the Convention Floor" interview at the DNC in Philly. The guy he's talking to is solidly pro-Hillary, says he feels she'd make a great president, can't wait for the election...
Reporter: "Are you nervous?"

Guy: "Nervous? Sure. It's not over until the last votes are counted."

Me: (yelling) "Except for the Democratic primaries, eh?"

Booming along...

I went to the range again yesterday morning with two different flavors of 10mm target ammo. There was the Prvi Partisan, which fires a 170gr truncated cone bullet at a claimed 1115fps, and then there was the Sig Sauer Elite Performance 10mm 180gr FMJ, which was considerably zestier with a claimed 1250fps muzzle velocity.

The difference in recoil was noticeable. On the unstippled Gen3 frame, sweaty hands were forcing me to fix my grip after three or four rounds.

All one hundred rounds cycled normally and there were no malfunctions of any kind to report.

This makes 150 rounds since the Glock 20 was cleaned or lubricated. 1850 rounds to go.

A New Beginning...

Pictures of the Glock 32 still need to be taken and its final eval written.

In the meantime, the next round of Special Snowflake Glock Testing is underway.

Next on the docket is a Gen 3 Glock 20 in 10mm Auto. It has had a hundred rounds fired through it since being purchased lightly used. It exhibited some of the same sluggish return-to-battery issues as the G32, so, rather than waiting 700 rounds to do so, this time I started out with a 20# recoil spring (which came with the the gun when I bought it used) on a metal guide rod. This time, a correctly thread-locked metal guide rod.

Oh, it's also had, like, fifty rounds of 9x25 Dillon through it on the spare barrel.

Anyway, a thorough wipedown of the bearing surfaces and a good lubing with what I had close to hand at the time (Snake Oil Prime) and we were off to the races.

Started things off with a 50-round box of Sellier & Bellot 180gr 10mm FMJ. Seemed reasonably warmish. Factory claims 1160 fps out of a 5" tube, and that seems plausible. I may have some more around here to chrono later this week.

I'd forgotten what massive horse pistols the big Glocks are... Anyway, all fifty rounds functioned the weapon with no failures of any type to report.

This makes 50 rounds since the Glock 20 was cleaned or lubricated. 1950 rounds to go.

Also ran fifty rounds of Remington FMJ through the Glock 37 with the T&E Overwatch Precision trigger in it. Lotta dry-fire Sunday morning and afternoon as well. I am intrigued; I need to get this thing out to MCF&G where I can do stuff on the clock...

You might find out your hotel room is built right atop a cursed graveyard.

Brunch Was Accomplished...

Turning from junk back into stuff...

I get emails from KEH Camera Brokers, usually offering the monthly or weekly sales, but sometimes soliciting purchases of old camera gear. Since I don't sell cameras, I don't usually look in those, but this one offering an extra 10% on 300 "Most Wanted" models caught my eye. What were these most wanted models, I wondered?

Nikon F4S, Nikon F5, Nikon FM2N, Canon AE-1 Program, Pentax K1000, Contax G2... Wow. And they were offering buying prices that I would have considered selling prices just two years ago, furthering my belief that the film camera market has seen its price bottom.

I'm still not selling them any film cameras, but if you have some lying around, here's their link.

Sunday, Yummy Sunday...

Plans are afoot!

We will greet the day with brunch at one or another of the fine eateries here in Broad Ripple, and then hie ourselves to Indy Arms Co. to enjoy some range time in the air-conditioned great indoors.

Project Whimsy has a TAC Trigger from Overwatch Precision installed for T&E purposes, with an eye toward making it my bowling pin eliminator. (Of course, I punked out of bowling pin shooting yesterday because it was hotter than dammit yesterday.)

Looking forward to trying out the new trigger, and maybe getting started on the next 2,000-rd test. Tune in!

Food Pic...

Still wrestling Winston's black dog today.

Bobbi did take me out for a late lunch/early dinner, which was nice. We rode our bicycles over to Twenty Tap, where I sampled a menu item I'd not tried before.
