I have a new Dan Wesson PM9. It shoots accurately and functions well (for a brand new gun on its first outing) with 135 coated and 125 plated bullets. The PM9 came with Metalform magazines with a spacer in the rear. It also came with a very long throat in the barrel. I can't reach the lands with this particular 135 and have any bullet in the case, but magazine length is the current constraint on cartridge length anyway. I was pretty surprised the 125s shot very well even with an even bigger jump to the lands. I see three different general possibilities for magazines - Metalform 10 rounders with the rear spacer (essentially what I have now but one more round), 38 Super mages without a spacer, or the "Springfield" type with the front ramp spacer built in. 1. I'm kinda thinking of a heavy blunt round nosed bullet loaded long in the 38 Super mags. What do y'all think? 2. And while I'm asking, what might be the intent behind a super long throat in a 9mm 1911? The finish on this barrel is just beautiful inside and out, it is a great piece of work. But the chamber is so different from SAAMI specifications or from a Kart 9mm barrel I compared to. Thanks in advance.
