As I have said in other post that I have years of shooting the LC9 pistols. And let me be clear on the fact that they are excellent firearms. The Nano is super easy to take down, but the Ruger is very easy as well, especially if you have taken one down as many times as I have. It does take a little more time, and you have to line up the pin and hole, but it becomes second nature very easy to do.I could probably do it blind folded. If fact, I just broke down each gun last night. I was measuring differences in the two guns and weighing different parts, like the receiver, barrel, thickness of barrel, grip and dimensions etc. I plan on doing a complete pictorial of the difference in the two guns this summer.
A few weeks ago, I went to the range with a few buddies and we shot both guns side by side with different ammo. 100 rounds with the Nano, then 100 rounds with the Ruger. and repeat. Both shot flawlessly. Both are as accurate as the shooter. However the Ruger does have quite a bit more recoil and especially muzzle flip. We found the Nano easier to get back on target. While I have been shooting the Nano quite a bit in the past few months, I have found that the Nano feels better with the grip. It feels more solid to hold. In fact I did not realize all these years that the Ruger actually does not feels not as solid as I thought.
The Nano really loves Hot Ammo and Plus P. That is where it shines. I have shot the LC9 so long for so many years, I have always felt the recoil to be light and even though it had a noticeable muzzle filp it is a great shooter. But after shooting a lot of rounds that day, I noticed that the Ruger started to give me discomfort, most especially with hotter ammo. I mean it was a distinct discomfort (not pain), The Nano however, felt as if I could go on shooting the rest of the day with no problems.
Triggers are alway's a subjective thing. My LC9S is measured at around 4 lbs. of pull especially light on the final very short and quick break. The nano has a little longer pull and and a 6.1 lb trigger. I have a range buddy that has been shooting his and has broken in to around 5-5.5 lbs. I actually prefer the nano trigger for Carry. And on fast shooting both performed well. The LC9s would be well suited for target work, if that is what you like. I do not target shoot my Carry guns and I personally NEVER ride a reset.
I posted before some pics for comparison. While both are great guns, the Nano is really built like a tank. Everything from take down pins, to the extractor, barrel ,recoil guide rod assembly etc. It was designed for the 40. cal and the pressures of the 40.cal.
And of course it is a modular design which I really like.
Example
Guide rods
chassis
Barrel is really thick. Weighs quite a bit more than the Ruger.
I will do a big review this summer with a lot of pics between a number of micro 9mms and hopefully some shooting videos.
But getting back to the OP. Congrats on the LC9S. They are terrific guns, very reliable and a whole lot of fun to shoot. It will serve you well for years to come. I highly recommend them. Sadly, I believe they are being discontinued, as they are not listed on their website any longer. So you were able to get one now. I guess they will still carry the buget gun at least for a while. I have no idea what they will come out with next. but the LC9S is IMO almost a legend.
