As I noted, the strong recoil spring MAY have been a characteristic of some of the earliest Super Match models. I've not read or heard of problems with later ones. It cycled normally -- just releasing the slide was a problem for me. It doubt it would be as big a problem with Bullseye as some of the other gun games.
I could make it work, but had to pull the slide back with one hand and depress the slide release with the strong hand. (The guy who bought the gun from me had strong hands, and he could do it using his strong hand only. He later got a weaker spring and it is now his CARRY weapon.) Go figure.
The P-226 X-5 I mentioned, as do all X-5s and X-6s, has a different recoil spring assembly than the standard P226 guns, so just getting a lighter P226 spring from Wolff was not an option. (If I remember correctly, Gray Guns seems to feel that the X-5 guns require the type of spring [winded/wound/twisted] that comes with it.) I didn't investigate the Wolff path with my P220 SM; it may, in fact, require a longer recoil spring than the standard P220.)
