Same here Nitrous. I want my pistols to shoot POA/POI at 25 yards. When needed, I adjust the rear sights for windage to achieve that. I rarely get a fixed sight gun that shoots to that POA/POI for me. I also install the proper height front sight to correct elevation almost as often. I much prefer low mounted adjustable rear sights that provide a sight picture similar to the old Bomars. Makes my life a lot easier. I have read posts about how adjustable sights are fragile, will get knocked out of alignment,etc, during rough use/combat. I get it, but have carried adjustable sighted handguns that did see some rough use. No sights were ever damaged enough to make them unusable. But if they had been, the gun would still be functional. I guess I've not been in the rough tough combat that so many on the internet have experienced;-)
BTW, I know many may think that pistols are sighted in at the factory. Not so much. With a new pistol design, testing is done to produce sight dimensions that the engineers believe will be in the ballpark for most shooters using common ammo. If all goes well, QC will insure that production guns are in spec. This is "close enough" for many,I suspect most, handgun shooters. Even if cost were not a factor, and the factory employed the world's finest champion shooter to sight in each and every pistol, for each and every buyer, using the ammo specified by that buyer, it would still not be possible to sight in your handgun for you. That is unless you were just plain lucky, and/or lighting, range conditions, wind,etc. were the same as yours and your shooting stance, sight picture, grip, trigger press, etc, was exactly the same as that champion shooter who "sighted in" your pistol. How about a machine rest? That really won't work either. It won't shoot to the same POA/POI as a human, again, unless you just luck out. I realize I'm in the minority of pistol shooters. But I've always preferred a handgun to be sighted in so that I know where the round will impact if I do my part, without having to figure "Kentucky windage" in what may be a stressful situation and, that if/when I miss, it's my fault........ymmv
