My Glock 30 didn't like 200gr SWC ammunition from Georgia Arms. After a very brief moment of being stumped by this failing, I fixed it for no money and with no swapping or modification of parts, despite not being a gunsmith or engineer: I stopped trying to shoot 200gr SWC Georgia Arms ammo in my Glock 30. You run into this all the time in the gun world:
Customer: "My BlastOMatic 2000 has started jamming a lot."
Helpful Employee: "Wow, you never had problems with it before. What kind of malfs are you having? Failures to feed? Failures to eject?"
C: "Well, it's started not getting the round into the chamber sometimes, and sometimes it stovepipes the empty case."
H.E.: "Have you changed your grip...?"
H.E.: "What about ammo?"
C: "I'm still shooting that Blammuntion-brand 225gr FMJ from those five cases I got a good deal on last year."
H.E.: "And I know you're anal-retentive about cleaning and lube... What's changed?"
C: "The only thing different is the 19# TacticalCo recoil spring I put in the gun."
H.E.: "Huh? The BOM2k ships with a 13.5# spring. Why'd you change? Had it stopped working with the factory spring?"
C: "No, but my friends said the TacticalCo spring was better."
H.E.: "Yeah, but why?
C: "I dunno. It was just... better."
H.E.: "Try swapping the old spring back in."
C: "Hey, that worked!"
Two bits of common wisdom that are common wisdom for a reason:
- "Doctor, it hurts when I do this!" "Well, stop doing that."
- If it ain't broke, don't fix it.
(PostScript: Not that there's anything wrong with Georgia Arms .45ACP 200gr SWC; it's still my favorite .45 practice ammo. Just not in that particular Glock 30. With literally hundreds of different types of ammo available, which is easier: Getting a particular gun to shoot the one kind it doesn't like? Or shooting the hundreds of kinds it does?)
