I've had model 37's for close to 50 years. Never had a problem. Although I have had and still have other shotguns I shoot a 37 the best. Having said that I've always wanted to try a BPS because they seem to fit me quite well. As others have said the BPS is heavier. I don't think you could go wrong with either. As always with shotguns buy the one that fits you best. Have fun shopping.
