By the end of the week I should have my first Walther. I couldn't pass up on the Shoot it, Love it, Buy it deal. It's a PPQ in 45 acp with a threaded barrel. I'm missing fingers on my left hand. On my Glocks and XDms (also striker fired pistols) I was able to purchase aftermarket slide end plates that extended out and allowed me to pull the slide back with the palm of my left hand. Does anyone know if a similar device is available for my PPQ? Thanks.
