What Metal Do Take Off

[johnny1gun]

I have a Springfield RO and CMC mags.The slide is locking back with one round left in the mag.If I take metal off the followers the slide wont lock back? I want to have the slide locking back after the last round. I know alot of guys disengage this function.(Why do they do this?)But I like to have that safty net when I loose count. So am I looking at taking metal off the slide release,and how do I know when Ive taken off enough..... When it works properly? Any advice would be helpfull. I shoot this in Single Stack and CDP. Also want to stay with in the rules.

Thanks, 1GUN

When guns lock back with rounds left in the mag, it's usually the profile of the bullet barely brushing it as they rise to the top. It doesn't take much to push the slide stop up enough to lock the slide to the rear.

Another more-professional option is to put a dimple on the rear surface of the slide stop. Look on that surface and there should be a vertical wear mark where the detent plunger rubs on it. The very top of that wear mark indicates where the slide stop is in its full-down position. Use a Dremel with a small stone and cut a small dimple there. The plunger will rest in that dimple, holding the slide stop down until it is forcefully contacted by the follower and pushed up.

Brownells makes a small detent cutter (if you're doing many of those jobs), but for a one-time-deal, the Dremel solution works.

FWIW . . .

I realize this was only a side question in the op. I've known folks who have cut the follower on CMC mags so that their gun will *not* go to slide lock when the mag is empty. Why? They have experienced, or talked with someone who has experienced, the frustration of overseating a fresh magazine (i.e., inserting a fresh mag too forcefully with the slide locked back). The result: the mag is stuck and the slide is stuck. As one can imagine, all the action on the stage stops and the shooter is left to push-pull-pry the mag out of the gun, while every member of the squad makes "helpful" suggestions or humorous (read: "derisive") comments (or both).

Good luck.
