Welcome, Charlie! How many are you looking to trade?
The small rifle primers will have thicker/harder cups to compensate for the added pressures seen in rifle ammunition, but I’ve used rifle primers in pistol loads without issue (did back down powder weight, as I would with a substitution of a small magnum pistol primer vs standard), so long as your springs are hard enough to set it off, that’s another Avenue you could try out. ?
I’d recommend not going the other way tho, slam fires and blown primers are possible if not likely.
