I've recently gotten a near mint Stainless Gold Match Pre Series II. It came with a 7 round magazine made by God knows who. It worked flawlessly with 7+1. I tried to make it jam and couldn't despite shooting it gangster style weak handed, limp wristing strong handed, you name it with both factory WWB and reloads (RN Rainiers).
Sure enough, I had an S&A magwell installed, changed front sight to a Dawson FO, and ordered 5 Wilson 47D mags.
Today at the range, disaster, FTF, FTL, had to really slam mags in. It just would not function reliably. Took it home, cleaned it (I had not done it through 300 rounds) and meantime left all five new mags loaded with eight round to hopefully set mag springs.
In sum, I know the topic must have been covered million times but what would you recommend? Jumping from the Empire State Building is not an alternative. But I wouldn't say it's not a big deal either. I want this thing to function properly. Do mags also need to be broken in? Any experience with Rainiers, Berrys, etc. What else is common in this cases?
Thanks,
Julio
