Here are my thoughts on the Ruger LC9......
I own a few 9mm with the Smith and Wesson M&P (Full size) being my favorite. The M&P for spring/summer wear is just to big so I purchased the LC9. I read the reviews on the LC9....took it with a grain of salt then experienced it for myself.
Its a small 9mm specifically meant for CC and short range situations so if you are expecting little to no recoil and a great target gun you are out of luck. Yes...it has a long trigger pull which does take a few shots to get used to, but once you have it down I did not find it difficult, inaccurate or concerning. In fact I ate a nice tight hole in center mass. There are conversion kits avialble to shorten the trigger pull, but its not enough of a problem to warrant me changing the trigger and spending more money.
I was personally surprised at how accurate and reliable the gun was. No F2F and she ate all the ammo I gave her. You need to have a good grip (you should anyway for shooting any pistol), but it is especially important in small hand guns or you will have F2F problems. This should not be your first hand gun nor should any small pocket size gun. This is not the perfect gun for the wife or significant other if she is not proficient with hand guns already. Small gun and a lot of power = jumpy.
I personally enjoy shooting the Ruger LC9 and for me its a great carry gun....very pleased. The price is right, its good quality,hides well with lighter clothing and has plenty of power. Smith and Wesson also came out with a similar gun called "The Shield" in 9mm. The Sheild has a shorter trigger pull and retails for around $449 which is pretty good as well. The LC9or the Sheild....flip a coin they are both great CC guns for the experienced user. Lots of great CC guns to choose from these days! Have fun!
