Kind of like Glocks myself and I've had nothing but long-term dependability with mine, but still found the Beretta PX4 interesting enough to buy. I have untold thousands of rounds through other autoloaders including the Glocks, but only 600+ through the PX4. Over the long-term, I have shot and seen dozens upon dozens of Glocks on various firing lines during my years as a police firearm instructor and I share your respect for their reliability.
My point emphatically is not to "sell" anyone on the Beretta PX4...or any other firearm. It is simply to accurately as I can relate observations and describe what happened. I do express my opinions in such matters, but label them as such...or at least try to so make no mistake: I am definitely not trying to act as a shill for Beretta. I have no financial interest in whether or not another sould purchases one; I simply thought folks who are considering something in this handgun genre might find the post of interest; nothing more and nothing less. How well the PX4 might or might not "fill a niche" for them will be their decision.
The PX4 has not caused me to run out and sell my Hi Powers, SIG-Sauers, Hi Powers, 1911s, HK's, Glocks and so forth, but neither am I ready to sell it for what I can get and try something else...at least not yet.
As mentioned, in the original report, I'm not sure if I truly "like" the gun or not, but it is still in the safe. It will take quite a few more range sessions for me to determine if it stays or goes.
