Slide Lock Malfunction?

[Rinehartdv]

I took the Texas CCW class yesterday. Fired 100 rounds total. WWB 230 grn. FMJ.
I used a Lwt SS Colt 1991 Commander. My mags are Colt SS OEM w/Wolff springs and Pachmayr SS rounded followers. We could only bring one mag. to the class.
The slide failed to lock back on an empty chamber, every time. Other than that it functioned fine and is more accurate than I am (Old-Fartism).
The combination of mag. parts has always worked well for me. I'm thinking about installing an Ed Brown mag. release and SS followers.
I don't use Wilsons, etc.,.
Any suggestions as to what could be causing the problem? Inadequate lube maybe? I going to clean the pistol and mag. and take all three magazines to the range. I plan on firing quite a few rounds thru each mag. Any positive suggestions would be greatly appreciated. Ray

i used to have that problem with my P-01 cuz of the way i was gripping the gun and the extended slide release... i was riding the slide release with my left thumb and the gun would slide closed on the last shot. took me a while to figure that out lol. maybe you changed your grip in the class?

You probably nailed it! Now I recall screwing around with my thumb positioning. I'll concentrate on a consistent grip @ my next shooting session. Thanks Butcher. Ray

Your follower is not properly engaging the slide stop ont the final round. Since you didn't have any failures to feed it is a magazine problem.

Why not try a Wilson 47D? It should take care of the problem. If it doesn't then sell it to a buddy.

You might try a Wilson magazine rebuild kit in your Colt magazine.

I had the same problem as you with a customized TRP. I'm using Wilson bodies with Tripp's Research springs and followers and have not had the problem again.

I'll find out at my next shooting session. Everything is cleaned and lubed. I'll pay particular attention to using a proper grip. If the problem persists I'll probably try the Ed Brown rounded SS followers, IF I can find them.
I'm not big on plastic parts. Ray
