I brought my railed version of my SP2022 into a shop today and started test fitting it in all sorts of various holsters. I mainly was hoping to find a black leather 3-slot OWB right side thumb-break holster. and I found one that fits great!...
DeSantis 001BAF4Z0 for Sig P229R with equipment rail. paid $59.99 for it.
first insertion was pretty tight. 3rd insertion it had already seemed to loosen up a hair. retention screw was fully tightened through this time. loosened the retention screw a couple turns, the 2022 went in pretty well, slightly easier than with the screw tight. I asked the gunsmith his thoughts on how much it would loosen up; he said just keep it in the holster for a few days off your body with the retention screw fully tightened, that should stretch it a little, then wear it for a few days with the screw still fully tightened, that should finish stretching it, then loosen the screw as needed. he said "in his expert opinion" it should stretch just enough to be perfect in probably a week at this time of year (cold low humidity new england weather in november).
muzzle end sticks out about 1/4" btw
and just for tonight while it's sitting in the holster stretching, I have a spring clamp on it to help it form around the slightly different muzzle end shape, every couple hours moving the clamp to a different spot, all the positions where it's a bit snug. I'm predicting it to work flawlessly within a few days, or less, as it's getting easier to insert/remove every time I move the clamp
