why are all striker fired pistols made of plastic?
 

Why are striker fired pistols always plastic? Im guessing to keep the weight down. Any feedback is appreciated

They're not. You just don't get out much. Striker fired pistols have been around a LONG time- longer than the polymer guns. Ever look at a Baby Browning, A Jennings- or a Luger?

H&K had the PSP P7. Interesting as it is a "squeeze cocker".

Colt All American 2000. Available as a steel frame or polymer frame. Bad timing on Colt's part. Introduced tight before the 10 rd mag limit law. Wonder 9's floundered for a while.

I see now
 

Guns and roses are indeed the greatest band ever! I should have been more specific. Why are all modern striker fired guns plastic framed?

Polymer is NOT plastic....

No disrespect, but I think you should listen to this video.....

The more correct thing to say is that plastic is a polymer but not all polymers are plastic.

Egg is a polymer.

The drive to polymer/plastic framed guns isn't only limited to striker fired guns. The trend in most handguns is gradually moving towards polymers. Mostly due to cost and competition in the market place. To remain competitive manufacturers need guns in the same entry level price point as competitors. So most introduce gunsthat are built to be competitive in price. Polymers help keep cost down. Striker fired pistols are also cheaper to produce because they often have fewer parts.

You could check out Sig for polymer framed pistols with more traditional hammer fired DA/SA and DAO configurations. And they run close in price point to striker fires pistols.

I stand corrected..sorta.
