Slide lock problem with a Rock Island (RIA) showed up last week.
The slide sometimes would not lock back on an empty Wilson Combat
Model 17 (now 290) magazine. It worked fine on a Wilson Combat Model
47.
The fix on my other Rock Island 1911 with a similiar problem had
been to get a Colt slide lock and install it. Problem gone with
both Wilson magazines and several other manufacturer magazines.
Still needs another hundred rounds or so before pronouncing it fit
for duty.
Ordered another slide stop from Wilson Combat for the current problem
child. It dropped right in but haven't tried it yet.
My Stupid Curiousity kicked in about that point. Checked the slide
stop position relative to the magazine follower after pulling the
slide etc off in my Colt 1911. Then reinstalled the RIA slide stop
in the RIA and noticed the magazine follower tab on the stop relative
to the follower was a little short. Swapped in the Wilson lock to
the RIA and a visual check showed the follower tab had greater
contact with the follower.
I don't have instruments to measure the dimensions properly so took
pictures. I used the same Wilson Model 17 magazine for all the
pictures. The Wilson slide stop SKU is 102B. Description: Slide
stop, 1911, .45ACP, blue.
I'm still an amateur at this stuff but this was interesting.
The Colt slide lock engagement.
The Rock Island with the original RI slide lock engagement.
The Rock Island with the replacement Wilson slide lock.
Based on results with my other Rock Island and these images the problem is probably fixed. A couple hundred rounds will tell the story.
Hope this works. First post.
