Got my standard BT380 Wednesday night last and shot 150 rounds through it yesterday. Really like that gun!
Anyway, to get back on topic-here's where I am at.
I would have to AGREE with posters on other threads that the STANDARD BT380 is a 'tad' large for pocket carry. Please make a note of that.
However, you can do it...
For instance, I have mine now in the left front pocket of a pair of Levi Wrangler jeans in a DeSantis Superfly (the 'Nemesis' with a cover flap). There is little, if any, noticeable print (no doubt, in part due to that cover flap).
However, the backstrap of the gun is pretty close to the outer rim of the pocket.
A person in grocery line immediately BESIDE your pocket carry side 'might' be able to see the backstrap (only about half an inch or less below the the curved rim of the outer pocket). Guess one might have to come up with a solution concerning that...
Inasmuch as I already have the Nemesis iteration-the 'SuperFly', (which I had originally purchased for my J-frame!)-I'm going to use that. The draw from the jeans pocket is clean in spite of the gun snug in there to the rear sights.
So, in light of my already having the DeSantis pocket holster - I don't see any advantage to purchasing an UM #3 or #4 pocket holster at this time due to the size of the standard BT380. I don't see where there might be any improvement in concealability so I am 'stuck' with that scenario anyway...
I would've ordered the UM #4 otherwise.
Hope this helps someone.
UPDATED: Just back-ordered the UM #4 anyway from Midway.
Will report back when received.
