The gentleman that used the pen name of Mark Twain once said something to the effect ... there are lies, damned lies, and then statistics ...
On a different note ...
You keep hearing about this 60% of L/E carrying Glocks, but nobody has ever provided the figures demonstrating the conclusive break down and justification for that 60% figure.
In the county where I work there are more than 20 L/E agencies going about their daily business. I've only seen Glocks in the holsters of some officers of a couple of them. A lot of S&W, Beretta, SIG and HK's, though ... some agencies associations have lobbied for the particularr choice of duty weapons, and some of these officers have told me they're allowed the option to carry whatever they wish (within "reason"). I don't see a lot Glocks, though ...
I was glancing through a list of all of the state patrol/police of the US a while back, and there wasn't anywhere near that 60% figure of Glocks listed as the issued weapon. It did strike me as odd, though, that there was a higher percentage of S&W pistols carried by the agencies. Why doesn't S&W shout this to the world? Guess they never thought they had to ...
NYPD has been reporting malfunctions with their G19's. According to a recent article, new NYPD academy graduates are now being given their choice of carrying either a S&W DAO or a SIG DAO, both in 9mm. Does that mean NYPD will be dropping over 25,000 G19's in-service? Who knows? Does that mean the G19 is a "poor" pistol? Of course not!
The problems reportedly being experienced by NYPD can probably be explained by ... recoil-impulse absorbing polymer frame, combined with short cycling (short recoil) pistol, with light slide mass but fast slide velocity, affected by a LOT of folks that may, or may not, have received the necessary training to avoid loose gripping/limp wristing a semi-auto pistol. Who knows?
Personally, I'm less concerned about brand name than I am about functional reliability, durability, compatibility with various different ammunition manufacturer's loads, ergonomics, ease of maintenance, available methods of carry, etc., ... and, well, price enters into it somewhere on down the line, all else being equal.
I don't care who else carries it or endorses it ... it's got to function reliably, and fit ... me. Isn't that what's important for all of us? Just because I've sent several thousand trouble free rounds downrange with a particular brand or model of firearm doesn't mean I expect you to want to emulate me. I'll give my opinion ... but it's your choice what you try and determine for yourself. Right?
