Anyway, I think I've deiced to hold off on a new purchase and use the LCP for a while. Now I'm trying to decide if I want my IWB holster to have a retention strap or not. I could see where it might benefit someone who "moves" a lot but I'm not sure if I fall into the category or not.
What are your thoughts on this?
I will never recommend a retention strap on an IWB holster. Your belt will cause enough friction resistance to keep the gun in place. The other purpose of a retention strap is to prevent gun-grabs. If you are carrying IWB, that typically means concealed so a gun grab is extremely unlikely (more unlikely than you needing to draw). If you have to draw, a retention strap will just slow you down.
Bottom line, stay away from retention straps when carrying IWB.
