.45 USP is hard to beat... I'm a YUGE fan and well it's an Hk so...'nuff said. Having said that--from my experience, the Springfield .45 XDm is every bit as accurate, no reliability issues at this point (only 10 years and a few thousand rounds down range though) eats everything I've fed it (just like the USP) and the mags are less expensive. It's weighty for sure...just like the USP. My XD came with interchangeable back straps. Enjoy your hunt and may the odds be ever in your favor!
