I briefly entertained the notion of a 17R for dry fire. Then I tried one. Trigger pull was yukky and resembled a mutant NY2 much more than my real gun's trigger. That is ok from the standpoint of tackling a difficult trigger pull, which is useful. But that's not the only way I want to practice and they cost about the same as a real gun, IIRC. I believe the trigger parts are also specific to the 17R, so you can't change around the trigger pull with readily-available OEM parts like on a normal Glock.

I just finished up some coaching with two lovely and talented young ladies. The SIRT was very useful on general, but specifically was useful for getting my point across about a decisive commitment to the trigger manipulation.
If the red takeup laser was on for more than a second or two before the green laser appeared, it was an indicator that they were agonizing over their shot.
I like the Blade Tech training barrels:

I'd need to look at them again to verify, but my recollection is that the Blade-Tech training barrel isn't going to do anything to reduce wear and tear on the firing pin or the breechface.
And they don't make a G34 length one, either.

Has anyone used the software from two pages back?
That's a good point. If Blade-Tech is going to make one for the G34, they could choose to redesign it so that the slide's breechface is supported by solid polymer (rather than nothing).
One could also choose to grind the end off of the firing pin, like in the P models.
