Issue guns with mil-spec M882 NATO ammo (About 36,250 psi, in the SAAMI +P range) are going about 17,500 for blocks, 35,000 for frame, 70,000 for slides. Expect more with SAAMI std pressure ammo (less than 35,000 psi).
Local USAF base has about 30,000 through most of it's guns, rarely break a block, rarely under 15,000, have never broke a slide.
