I don't know much about polymer pistol frames (yet), but I do know a bit about polymers. When a manufacturer says "polymer frame", what do they mean? What polymer? Some are more suitable for this particular application than others. If the polymer is polyethylene or polypropylene), solvents can't do much to harm it. Want proof? Concentrated acids (H2SO4, etc.) are shipped in polyethylene bottles--just check at your local Ace Hardware store. These are low cost, light weight, high performance thermoplastics with a range of physical properties which can be altered to an amazing degree by the mixing in of additives (talc, glass beads, etc., which makes them tougher and further lowers the cost.) Probably the only reason we don't see polymer slides is that they don't take heat well (so far).
"Polymer Frame: What does it mean? "
To me it means plastic gun. I do NOT do plastic guns!
Polymer is a sufficient , lightweight material for its intended purpose.
I suspect that Glock uses a glass-filled polypropylene, but I don't know for sure. Hence the question--what DO they use?
Read my statement that you quoted.
I did. So are you saying your statement is stupid?
Polymer framed pistols are just as safe as metal frames... i've never heard of anyone having an issue/problem with a frame simply because it was polymer (and not due to some other issue). I understand that some have not warmed up to the idea of polymer pistols... and may never. Some people still use a weaver stance and do the tea cup & saucer grip as well. To each their own I guess... some adapt and change as we make advances in training and construction materials and others stay stuck in a certain place in time... refusing to accept progress or new ideas.
Don't get me wrong... more than half my guns are all metal (Sig/Beretta/CZ to name a few), but polymere is strong, light and durable.... they've been around long enough and used in the field long enough that that FACT is hard to dispute...it is not a passing fad.
I love my Kahr CM9 and M&P Pro (polymer frames)... and rely on a Glock 22 to protect myself or others on duty. So far no issues since the mid 90's when most departments started utilizing em'.
Speaking of the Kahr, have you had any issues with it?
Nope... smoothest double action i've felt on a subcompact yet. It's more difficult to break down than a Sig, M&P or Glock... but it's not like I plan on field stripping it on the street in a hurry. Small, reliable and light... and 9mm... just what I want.
OK...I've been looking at them for a placement gun, per se...you know, have a weapon where you need it kind of thing. Tea pot, etc, but don't want junk.
Btw, polymer and plastic aren't the same material. Anyone who calls polymer frame guns "plastic" really do themselves an injustice.
