I've always been a fan of S&W and Sig's. With that said, I do believe that each has its place in the service and CCW market. Sig is known for being a solid firearm right from the get go. I own a P220, a P226, and P229 as well as a couple of their 1911 models. Great pistols overall. S&W has, well, a long history of being reliable weapons which, if you consider it a plus, made here in America. I own a M&P9c and owned the M&P45, 642 and 442. Sold all but the M&P9c. I've been able to shoot both the P238 and own a bodyguard 380. I tried both out before deciding which to buy. Not to mention, I've owned the LCP, TCP, Keltec, Walther, etc.
P238, beautiful little pocket pal. So many variations available now that you can suit it to your individual taste and desire. Decent little shooter and a familiar design if you are a fan of the 1911's.
Bodyguard 380, this has to be the smoothest and softest shooting 380 I've ever shot. So far completely reliable. The grip is long enough to feel comfortable in my hands (i wear size large/XL gloves) It has actual sights that are easy to see.
Weight goes to the bodyguard. Fully loaded in a comptac holster and it pretty much disappears when I have it IWB. The p238 has a bit of heft to it considering it is only a 380.
Sights to to the Sig. Night sights are always a plus.
"Prettiness" goes to the Sig but the Bodyguard isn't too far behind. The various models of the P238 give it the edge though.
Trigger pull goes to the Sig also. It is just nice and short (again 1911 fans). The Bodyguard is a true DAO pistol and the pull is longer and heavier but for me, considering it was a pocket gun, I liked it.
Shooting, well, like I said before. I found the Bodyguard to be more consistently accurate and softer shooting. Surprising considering the p238's frame.
Accessories, this is a tough one. Sig always has more options which I really don't consider accessories but they can be viewed as such. Bodyguard comes with the integrated laser.
Holsters are available for both models in various designs ranging from IWB/OWB/pocket tuck/rear pocket/neck wear/ankle.
Price goes to the Bodyguard. You can find the S&W for less than $400. The Sig starts at over $500. That depends on your piggy bank.
So why did I go with the bodyguard instead of the p238. Honestly, I felt the S&W a bit more comfortable in my hand and it was more of a consistent shot for me. Maybe the P238 was slipping in my hand but it did not shoot as consistent as the S&W. Also, the fact that it came with the integrated laser was a BIG plus. Though, I have yet to actually have it on while I carry it. Price was also a consideration. Did I really want to pay $500-700 for a 380acp? I didn't. But you may. Is the sig name for a 380 worth the price difference? To ME, considering the bodyguard shot better and had the laser, it wasn't. The decision is yours in the end but I wanted to give you my opinion on it. Again, this is my opinion. Either way, good shooting mate!!
