Subcompact guns need frequent spring changes every 500 roumds or so. They arent designed to shoot lots and lots. Most will.go.the distance but you have to be mindful of maintanence and do frequent inspections.
There just is not enough slide mass. Thats why they have strong springs. Ill fire 50 rounds thru my colt new agent now and then for familiarization but the manual of arms is the same as my full.size series 70

The problem with being stupid is you cannot simply decide to stop doing dumb things...
