I have the crossbreed supertuck for my shield I very comfortable at the 5 o'clock position. I also have a jm4 tactical that it pretty comfortable, I wear that one in the appendix position but I am fat so not super comfortable on long rides but it very easy to take the holster out and put it in...
.257 ammo is pretty hard to find I grabbed a couple boxes from midway last week. the cabelas by me had 1 box of new brass if its there I can snag it up for you if you want.
I still use them for regular banking, but got rid of my insurance through them it was good in CA then I moved to Ohio and there rates were garbage so I switched.
Man do you guys drag those down a dirt road, mine has been in the bed of my truck for 6 months filled with gear unsecured and it just dirty. They are like 2 years old.
I would pull it out and replace it, your wall is already opened up and its an easy job. If its brand new and leaking it's most likely going to give you more issues in the future.
