I do not like inside the waist either. I also think it slows things up, and I am a firm believer in being the first to fire. We all have different opinions based on our experience.
That said, I do use a groin holster for one of my backup guns, as well as an extremely slow ankle carry for another backup gun. My extra magazines for my primary gun are usually inside the waistband in the summer.
I am amazed that you can hide your Ruger in your jeans because I can't really hide my Baby Browning which is considerably smaller. It may be the difference of the cut of the jeans since I alway wear stretch denim as well especially since I want mine tight. I like to be able to move in them and that I could not do very well if they were not stretch.
If I did not already have a Seecamp 380, the new Ruger would be my choice for a smaller backup gun.
Your jeans must be skin tight...
I own three pairs of Wrangler Bootcut stretchy jeans (the worst kind for printing), regular fit, all the same size.
In two of them, LCP (in Ruger pocket holster or a Sticky holster I just bought) doesn’t print. You can see that I have something in my pocket, but it’s actually less noticeable than my normal size wallet.
In the third, the pocket is either a bit smaller, or sewn differently, and sometimes the grip prints. But you’d have to really pay attention to see it and know what it is. Using a flush mag plate (the one without pinky rest) helps.
In most of my shorts, it’s impossible to see that I have anything in my pocket at all, and none of them are baggy.
By contrast, I pocket carried G26 in a Remora, and while it didn’t print as a gun, in these jeans it did stick out like a really fat wallet. I.e. looked ugly and drew attention, even if you wouldn’t be able to say what it was.
To me, LCP is carry heaven. I am 5’-10” and somewhat overweight, pushing 215, and IWB with Glock is just not comfortable. I can find a spot that feels OK, today, but the same spot would be very uncomfortable tomorrow. And the biggest problem is driving and sitting down, which I do all the times throughout the day. So I can carry my G26 if I am meeting friends for dinner downtown (and driving through some pretty bad areas along the way, not a place to have a car breakdown), but there’s no way I can comfortably carry it daily, every day, without going OWB. And that’s a whole different set of issues.
With LCP, I can just throw it in my front pocket, and it’s indistinguishable from a moderately sized wallet.
