First, after learning more about free-float tubular forearms than a human should really ever want to know, I have it installed securely on Little Panther. It would take me several hours to type out the complete procedure, which included adapting rails that never were intended for carbon fiber, and modifying the "official" tools so that they would actually work as advertised. This was a DPMS .308 barrel wrench and a DPMS .308 carbon fiber handguard, but they wouldn't work until I made several "adjustments". The final results look good, but do not show all the sweat that went into this "simple mod".
Most of my quality time with firearms has been spent with handguns. The more I ponder how concealed carry should work for me, the more I'm convinced that I have to leave my gee-whizz-but-still-beloved P7 at home, and carry my S&W J-frame Model 60. A pocket holster works best for my needs, which includes the ability to carry it at all times without thinking about that heavy piece of steel on my hip, and my mussed-up shirt covering part of it.
Then I stumbled upon reviews of the S&W BG38, a J-sized revolver that is otherwise a complete break with the last 150 years of S&W revolvers. The EBW emporium had it in stock, with one available as a rental. I rented it, bought an (overpriced) box of their target ammo, and shot the BG38 along with my Model 60 (after unholstering it only on the firing point).
I was getting used to the Model 60 in my pocket, but at 25% less weight, the BG (bodyguard) 38 made itself at home even quicker.
While this model has had mixed reviews (one whiner said that he could not get any one of three he tried adjusted so the laser coincided with the point of impact at 25 yards), my side-by-side shoot-off said they both handled the same, with the BG38 having the advantage of sitting about 1/2 inch lower in my hand. The barrel liner, cylinder, and internal non-plastic parts are stainless steel. The front half of the frame is some sort of "unobtanium", and the trigger guard and everything behind the cylinder is plastic. It is not supposed to be disassembled, but I have my theories already. I'll just wait until someone else posts it on Utube, rather than pioneer on my own.
It now lives in my pocket holster, and the 5 ounces difference in weight means I'm still aware of what's in my pocket, but it doesn't feel like it's pulling my pants down. Which is more than I could say about the undercover cop with the donut belly, and his Glock in an IBW holster. I could just about read the serial number through his T shirt. If I carried like that, I'd lose my license, and weapon, forever.
