First, I very much dislike striker fired autos, particularly Glocks, so let's get that up front. For you folding knife guys, I equate them with liner locks. Some are very good, but the overall design leaves a lot to be desired.
My chief gripe is that the firing pin depends on a longish spring which, when depressed, is released by a squeeze of the trigger. The spring then releases, sending the firing pin forward to contact the primer. The gun goes boom and the whole thing can be repeated until the magazine is empty.
Not only does this put a lot of wear and tear on the guns, Glock recommends these springs be changed every 3,000 rounds. Hammer-fired pistols fire when a hammer or hammer block contacts the primer, which in turn is driven forward by a shorter, stiffer spring that far outlasts the longer striker-fired springs that bypass the hammer.
Another thing I personally dislike is the so-called safety on these guns. On the Glocks, they put the safety on the trigger! This is akin to putting a brake on an accelerator. Every police department, highway patrol, federal or state LE agency or security service that has gone from revolvers or hammer-fired autos like a Beretta or Smith & Wesson's superb 2nd/3rd generation pistols, has seen a substantial increase in accidental discharges.
Can Glocks and its siblings be carried safely? Yes, with a little extra training, but though some people feel safe carrying them and using them, others (including some gun savvy people) don't. I've taken my Smith 659 and 3906 pistols and, unloading them, I cocked both. I then set about trying to get them to "fire." I then took my sister's Glock and did the same.
Given the Smith's long takeup in its trigger (even cocked), I found that accidentally discharging my two was no more or less difficult than accidentally discharging the Glock! In fact, I cocked one of the Smiths and carried it around both casually (under the belt in front and back) and formally (in a holster). I then took the Glock and did the same. In both situations I would have felt uncomfortable carrying any of these guns thus described. Also, if I were a police chief or agency head, I would have severe doubts about letting my personnel carry striker-fired pistols. If they're not cocked, they would have to be before being ready. And if they are cocked, firearm retention becomes a significant issue.
Hammer-fired pistols are much more reliable, safe guns than any striker-fired pistol. So I'd pass.
Just my own personal view.
