Built like a tank ... Just picked this up from my FFL. Ruger P90 .45. Snagged it on GB for a bargain price. Stoutest semi auto pistol I’ve ever owned, I don’t think you could ever wear this thing out.
It should be a "tank," if you understand the history of the P90's development.
Ruger's initial P90 prototypes were engineered to withstand the pounding of 10mm ammo because that was intended to be the gun's original chambering, until the .40S&W appeared in 1990.
Ruger canceled on offering a 10mm model, and the large-frame P90 was then rechambered for the low-pressure .45acp. Another model was offered in .40S&W.
Bill Ruger shouldn't have been so short-sighted.
... Like Glock with their G20/G21, and S&W with their 3rd Gen 45XX and 10XX guns, Ruger should've have completed his 10mm P90 project and then offered that model in
both 10mm and .45acp.
Instead, he drank the "
10mm is a dead round!" coolaid being served up by the late '80s/early '90s gunzines, ... and the rest is history.
