I have decided that my next handgun purchase will be a Beretta PX4 Storm in .45acp, however I can't decide if I should go the extra $450.00 for the new Special Duty model, or just go with the standard full size .45acp model..... The SD (as I understand it) comes with a nice tactical hard case, a third magazine, the faded dark earth frame which is only an appearance factor, and a half inch longer barrel, but an additional $450.00 for those features doesn't quite add up. I can get a third magazine for less than 50 bucks..... Unfortunately there are no ranges in my area where I could test fire both to compare, out of the half dozen gun shops even remotely close to home, only one was even interested in special ordering the SD, but I'd have to drive there and give them a health deposit before that would even happen, so I can't even just check one out at the counter.... Does anyone here have the SD model PX4, and if so in your honest opinion is it really worth the extra $450.00 over the standard full size PX4 Storm in .45acp.....?
