Both are Wilson's Officer size. I put the lower profile base pads on them. Still trying to make up my mind about them. I have about a dozen Springfield magazines from CDNN Investments (around 10 bucks a piece) that work and 3 or 4 Colt Officer ones (also from CDNN) that don't have bumper pads.
What I usualy do is buy about a 1/2 dozen mags from CDNN. The ones that work get the springs replaced with ones from Wolff. The ones that don't get thrown in a box next to all the holsters that I have collected over the years that didn't quite cut the mustard. The next range trip, I'll take the new ones with me and try them out. Any that cause problems there also get thrown in the box when I get back.
What I have found is that usualy the screw bushings are a tad too long, especially on Springfields. I keep a supply of bushings on hand and when I purchase a new pistol the factory ones come off. I stone a new set so they fit slight below flush and then use blue medium strength Permatex threadlocker on them. All the 1911 style pistols I have have had their stock stocks replaced. I put some blue threadlocker on the screws when installing them and as of yet have not had a screw back out on me. I can still get the screws off and remove the stocks to clean the pistol. When I'm done, I just put a touch of threadlocker on the screws again and tighten them up.
