AA conv'n magazines - again

Heads up on fit -Forgot to mention in prior post:
I got more of the AA conversion mags from Lanbo's Armory (best price-on mags and Target Conversion too). ----Order went well-shipped next day-typical UPS timeline. -- https://lanbosarmory.com/index.php?main_page=product_info&cPath=3&products_id=11405

Now:
These magazines-and my 3 earlier ones don't/didn't fit  freely in all 1911 frames. As delivered they Fit & fall free from the Baer, Kimber; Too snug in the Caspian XR & Springfield. A little time with file on the sides and they work in all frames. - With my skills, filing is way easier than lip bending.

prior post: 
My later model AA Tgt conversion does well with CCIsv - it's been reliable. It locks back, w/right recoil spring ( has steel insert).  
I use AA conv'n magazines exclusively in the AA and my old Marvel. -- 
One thing with the poly mags: eventually they wear (round off) at the mag catch slot(?) and a couple of mine now won't always stay in the KImber frame.-These days I hold the mag release in when I insert and < dropping mags.-Not a bad idea regardless?
2¢ - YMMV
