I use Small Rifle primers in place of small pistol primers. They seem to work the same in all of the guns I shoot them out of. When I started reloading during the primer drought they were all I could get. Though make note that none of the loads I use them in are over middle of the road for pressure and velocity. Also I carefully worked up the loads as well. Since I load a lot of rifle rounds anyway I never bothered to pick up small pistol even when they became available due to the fact that I already have loads worked up that work.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
