No, it isn't. I have a Glock 20 as my first 10mm and it didn't shoot well. I had to replace the stock barrel, with it's polygonal rifling, with a Storm Lake barrel that uses conventional rifling to accurately shoot the 185gr reloads I had. The Glock also didn't have a hammer, which I prefer to have on guns, and I didn't like the glock action. DA actions like the Walther P99AS, worked better for me.The Glock (and I'm not a Glock guy) is a great option.
I have an Armscor 1911 in 10mm. This is the gun I bought several years ago, but it was an earlier version: https://www.armscor.com/firearms/ria/rock-series/rock-ultra-fs-10mm/I’m definitely open to a 1911, I just recently picked up an SR1911 in 45acp and it’s beautiful. I think I want to stay within pistols and not a revolver. Now the fun of trying to find local stock begins
I've only been able to shoot it once after buying it since I've been working overseas for the last few years, but the gun shoots well and feels solid.
