Pro mags are so bad I'd rather single feed.
because unlike the OP, there are suckers born every minute. always somebody out there looking for a cheap something and no first hand experience so they roll the dice and end up buying McGar et al. down the road anyway. the same with holsters. neophytes don't want to spend $65 on up on a quality holster so the nylon uncle mike's stuff count's on them.I don't think I have EVER encountered a ProMag. If they ARE so bad how do they stay in business?
I bought three Pro Mags for my Bersa 383A when CDNN had them on sale for $13.00 each. I had to perform the same modification. They all performed well after that.The only ProMag that I own is one that I bought many years ago for a Bersa 383A (predecessor of the Thunder 380). Bersa mags were crazy expensive for such an inexpensive little gun, so I bought the ProMag.
When I first tried it, the mag's feed lip interfered with the slide stop, and it wouldn't seat correctly. Some judicious and careful filing solved that problem, and it worked 100% after that. It's still in the gun.
I never bought another one, though.
