Hey man I get it. I’m definitely not where I want to be weight wise either, and I’m working on it. Kudos to you, and don’t lose your determination! There will be days where you feel like nothing is working. But this is a marathon, not a sprint.
This is the holster I bought specifically for the LCP. I got the larger size, and it works great for the LCP. Anything bigger though and I’d recommend one that has a calf strap like this one.
