“Not so. The first polymer P-Series was and is also the last. The P95 was named after the year of its introduction - Ta Da - 1995. The .45 caliber P97 came along in 1997. Now you may be right considering the SR series, I'm not sure.”
My goof, I should think more before posting.
“I've never heard of a broken frame on a polymer P series Ruger.”
I never seen or heard of frames cracking or barrels breaking on the alloy framed Walther P5 until fairly recently. Not really bad considering the pistol was developed by 1977 and available here since the early eighties or so. Cracked framed P5’s are those of the Dutch police using heavy A3 and Action Effect ammunition.
“Some do, some do not. They replaced the barrel link with a "cam block" arrangement somewhere in the middle of the series.”
The P95 appears to use the cam block you speak of and the takedown pin appears to anchor the locking block that is integrated with the recoil spring guide. Interesting change and wondering whether it’s related to the frame material change.
