I'm an old (some would say, "Very Old"), 1911 guy who compares any auto-loader to the grip feel, width, reach to the trigger and controls to that pistol. That said, the Hi Power is my hands down favorite pistol for it's feel in the hand. It was the fore runner to modern high capacity pistols and had a 13 round magazine capacity for decades. I carried one for the bulk of my first tour in Vietnam, 1970, and it was literally never out of arm's reach during that time. It has the weight to absorb 9mm recoil easily, yet not so much as to weigh down your gun belt.
Back to the the grip...I have size "L" hands according to the work glove size that I buy. Any 1911 fits me well as to trigger reach...short trigger or long, they are no stretch nor am I forced to extend too far into the trigger guard with either. The Browning, and now Springfield SA-35 have the same 'reach' to the trigger for me. In a word, they're as comfortable as the 1911.
I think Charlie said he found the supplied factory grips on the SA-35 a bit on the thick side....I did as well, and replaced them with Hogues (see pic below), which are a bit thinner than either the old standard BHP or the Springfield factory grips...While the SA-35 is thicker through grip than a stock 1911, it doesn't feel that way in my hands.
Lastly, the feel of the gun, the sights and most importantly, the safety size and location on Springfield's SA-35 copy of the BHP, make it a superbly accurate 9mm. Individual specimens vary, of course, but my SA-35 is the most accurate 9mm I've ever owned. With over 1000 rounds without a malfunction of the gun, it's also the most reliable of all my auto pistols. Laugh if you like, I'll admit I'm a fanboy for sure, but the SA-35 a hellofa gun. Best regards, Rod
