If a better grip on the slide of your semi-automatic pistol would help, Arachnigrip may be for you. The slides on some pistols are very difficult to pull back, especially compact and sub-compact models. If you've "been around the sun" a good many times, they can be even harder.
Arachnigrip is a simple, inexpensive product that works as advertised to help make chambering a round in your pistol much easier.
I ordered one, they actually sent me 2 in case I messed one up, for my Kahr 9mm. I love that pistol but the slide is tough to pull back to load that first round.
It's really easy to install. I did not get mine perfectly even but it works and since I'm really trying not to be so obsessive, I left it just as it is. I can't tell you how much it increases my grip but I can tell you that grip is no longer a concern.
In the event that you have arachnophobia you can get the slide without the spider. Personally, I like the spider but then again...
