I have a SW40 that I FINALLY got a chance to shoot, and I find that it's shooting pretty low. Granted, I don't anticipate shooting it at any distance greater than 7 meters, but I do want it zeroed where it should be.

Problem is that the SW40 doesn't have adjustable sights. I've been shooting Federal 155 gr Hydra-Shoks in it, and I'm going to try some 180 grain loads to see if the increased dwell from the lower velocity brings the POI up.

Failing that, what options might I have with regard to the sights (are there replacement adjustable sights out there for this pistol?).

Thanks!

It might be these sites are "combat sites" with the point of impact at 6 on a clock face instead of centered. This is "minute of man" rather than target accuracy. They take getting used to if you haven't used them before. Use the 155 grain ammo if that is what you prefer. It's easier for you to adapt than it is to change sites or otherwise modify the gun. As the Air Force recruiters say, "Aim High."

Good point - I didn't think about the "minute of man" angle. Makes sense though that a weapon like the Sigma series would be designed to put shots where they would be more likely to impact the center of mass. But like I said earlier, I'd be firing at lethal-encounter distance rather than 25 yards or so. Wouldn't matter if the sights weren't exactly zeroed.

I have some Federal 180 grain loads on the way - I'll see how they pattern as opposed to the 155 grain. If I wind up liking the 155 better, I'll put the 180's through my Hi-Point carbine.

heavier loads may shoot higher, and i think hotter loads will, but i get the hot/mild equation backasswards sometimes. someone else will chime in....... but i think you can find the ammo to get you close.

In a handgun, slower loads will shoot higher because they have a longer "dwell", or time in the barrel. The longer a bullet stays in the barrel, the more its trajectory will be raised as the recoil lifts the gun barrel. That's why I'm going to try a slower, heavier load. But like Alan said, it's probably a matter of the gun having combat sights rather than target ones.

o.k., i'll buy that. i usually get it bass ackwards.

Is that the model? SW40? If the front sight is removeable, you may be able to purchase a shorter front sight blade. If it is not removeable. You can file the front blade down a little. That will raise your POI in relation to you POA.
