Hi all, I recently aquired a 1952 Sistema Model 1927. After a new barrel, bushing, hammer and trigger it's running great. The only issue is the gunsmith who did the trigger lost the mag that was in it, nothing special, a blue Chip Mccormick shooting star. That mag worked just fine. They gave me a stainless Wilson Combat 8 rounder to make up for it. However, that mag, along with a 2 Kimber Tac Mags will not lock in with the slide closed. I have 2 old Checkmate 7 rounders that I can carry 7+1, they insert just fine with one in the chamber and my 10 round Wilson works as well. Has anyone else had this issue?

Just about everybody.
The typical 8 round 1911 mag is the same length as a 7 round mag. When fully loaded that is a lot of pressure on the spring and there is very little room for the spring to compress any farther. Remember, when the slide is closed, the bottom of the slide is pushing down on the top round in the mag.
You can thumb cycle the rounds in and out of the mag many, many times, or just shoot them a lot. Eventually they will become easier to seat as the spring takes a set. However, they may never be as easy to seat as a 7 rounder.
Your McCormick Shooting Star probably was easier to seat since it was an old, broken in mag.
The new generation of 8 round mags, such as Wilson ETM and Tripp Cobra Mags are designed as 8 rounders and are thus longer than Wilson 47D's and McCormick PowerMags. The longer mags will be easier to seat as they have more room in the tube for the spring to compress.

Some mags need some power behind them to lock in if they are fulled loaded and the slide is closed. There is nothing wrong with putting some muscle into it. Just don't slam them up there with the slide open because you and jam your gun or possibly break your ejector.
