Hi Randall_G, your magazine issues could be a number of thinks, both together, or alone? First we have to discuss the Mec-Gar magazine a little to get a starting point to our journey of descovery. Meg-Gar P.08 mags are slightly undersized compared to original P.08 mags. And this is by design, as a slightly undersized mag shell (1.095") will fit most with out issue, an oversize shell, or a "stretched " out original 1.110" will fit none? So, if you have a Luger with a slightly large mag well, maybe .010" over at 1.110" and a mag slightly under, at 1.095" then you have a .015" to .020" jiggle space. Doesn't sound like much, but it is huge on the land of, "catchey, stoppy things"
. Other considerations are, the mag catch button its self? It it rounded at the catch point and does it have a good profile in the mag well to interact correctly with the mag shell? Another consideration is the mag catch button spring. Is it full strength or soft and weak ? If'n it were me, I would apply some type of aluminum tape to the rear spine of the Mec-Gar mag, building it up layer by layer untill the mag slides in nicely and stays where its supposed to when sending down range. It's not a cure, but it is a difinitive test to let you know where you are at! BTW, you can field strip your Luger, and also disassemble the Mec-Gar and install, then look inside to see how much contact you have and go from there... Best to you Randall, til......lat'r.....GT
