Tom,
In order of date acquired I have:
G22 - 1990 - several thousand rounds, nearly all full power factory or reloads, thru it and have only used the stock recoil guide and replaced it once (Glock captive unit). It originally came w/the two piece unit. No signs of frame battering or excessive wear.
G27 - 1996 - 5M+ rounds, mostly factory w/some full power reloads. Replaced factory recoil assembly w/another factory assembly last year(Glock). No signs of battering or excessive wear. I have also shot this gun w/a G33 bbl. using full power loads and on Glocks recommendation, I used the "stock" recoil assembly (same for both guns).
G35 - 1998 - Over 10 thousand rounds of factory full power, reloaded full power and reduced power. I used this frame for my 24C upper also but with a reduced Wolff spring and guide rod for reduced loads in GSSF competition. Still using the original factory recoil assembly as a G35 and again, no excessive wear. I am considering replacing it soon however but only due to it's age not problems.
I also have a G32 that I use a G23 bbl. in (bought it from you I believe) with the stock captive recoil assembly. Not as many rounds as the other guns but it works just fine w/all types of ammo.
