That one has had a few issues Prickett!...the slide being the issue of focus to me...
But that draws me to the conclusion I have always had regarding firearms, or any mechanical device for that matter.
If we are to depend on a mechanical device to save, or protect our lives, we must keep them in top notch shape as best to our abilities, and when that device is dependent on another manufactured product (ammo) we must buy quality items to help ensure our mechanical device operates as intended!
With all of that embedded in our minds, we come to the crossroads of reality and we must always have plan "B" for when we have bought the best in mechanical devices (firearm) and bought the best in essentials for it (ammo) and it fails One time when we need it most, due to elements beyond our control (these are endless) but reality, we must be ready to implement plan "B" when our devices fail.
I "trust" my firearms... I "depend" on my ability to implement it for its ability, with the knowledge it can fail!
