...any product with instructions that require you to use a power tool is not what I would consider "drop-in".Remember, the claims on the packaging are actually in code:
- "Drop-In" really means "Some Fitting Required". (Either that, or it's so undersized you could drop it in from across the room.)
- "Some Fitting Required" really means "Take it to a gunsmith."
- "Gunsmith Fitting Recommended" ...and bring money.
