Finally got it back!

Hey gang,
Jus got my jam-o-matic RIA 10mm 1911 Tac MS back from ria...it is the commander size version with the light rail. When I first got it I posted that it jammed about 4 times each magazine I only had one mag at the time but it didn't work with the 45 mags tried either...got it back from RIA today...they said it had a bump on the feedramp and extractor was out of spec

Wait a second! You tried .45 ACP mags in a 10mm pistol and expected them to work? Granted the pistol was at fault for being out of spec. but the 10mm mags and the .45 mags are two different beasties. Problem is, either one will fit in a 1911 type pistol. My Nephew screwed up with me on a range trip once and wondered why the .45 loaded mags weren't working in my 10 mm pistol. (I had both a Dan Wesson Razorback 10mm and a Springfield Armory 1911A1 GI .45 ACP that day. Both are stainless steel pistols and look almost identical)

thanks Harley, I tried this today everything look to be in order. I went out and shot another 5 mags through it and only one mag didn't lock back. Could be because I was doing a rapid fire drill. I tell you the more I shoot this gun the more I like it. This is quickly becoming one of my favorite handguns. This 10 mm round kicks ass!

It may also have a weak spring

I know it has the factory spring. ..maybe I will try to get a stronger one...will have to read up on them. .I know 18-22lb springs have been mentioned but I still want it to work with the lighter factory stuff

I was meaning mag spring it may not be pressing the slide stop up fast enough.

Actually it is quite common to use 1911 45 mags in a 10mm with success.  I have done it in the past with no problems.
