    Will the 165gr have less recoil? Is the 180gr just better?

    Generally 180gr has less recoil, but it depends on the powder that is used.

    There is some ammo (made by Federal) that is lower grain but it is marketed as "low recoil" but my understanding is the penetration is not as good with this stuff.

    Hmm...THIS ought to generate some traffic.

    Personally, I prefer lighter bullets, but probably for no good reason. In 40, I loaded and carried 155 Hornady XTPs, and in my .45GAP I load and carry 185 Gold Dots.

    ALL the bullet weights work just finely. Recoil probably is proportional to the muzzle energy of the load. Unfortunately, the velocity achieved by some factory loads is substantially short of those achieved by real pistols shooting those cartridges.

    That's not entirely true. The Federal Hydra Shok 135gr "low recoil" ammo is 1200pfs at the muzzle and it has the least recoil of anything I have ever shot. I think it has more to do with the powder mix. For instance, with Gold Dots, the 180gr is a little less recoil than the 165gr, but the 155gr are very hot and have quite a kick. There is less difference between the 155gr and the 165gr in weight than there is between the 165gr and the 180gr, but the recoil is much, much higher in the 155gr.

    It just depends on what 165gr vs what 180gr. I find the higher perf ammo in both about the same for recoil.

    165 SGDHPs out of my G27 are snappy; 180 SGDHPs less so.

    Out of a G22, I couldn't tell the difference

    I was listening to a ProArms Podcast in which Mr. Ayoob interviewed a LE veteran who said the vast majority of self defense shoots were frontal shots where lack of penetration wasn't an issue. ymmv

    :agree:

    With most rounds, most likely. The problem is when you get these ultra high velocity rounds that fragment.. thus resulting in less penetration. Not to mention if they start going through heavy clothing, etc.

    Personally, I prefer "heavy for caliber" loads.

    and most bg are not standing still or giving your a perfect frontal target to shoot at, if you are in a personal defense situation. "Heavy for caliber" for better penetration at any angle .

    Light wt FMJs for competitive shooting

    True.

    The interviewee's favorite round was the Federal Tactical Bonded 165gr.

    When I first bought my G22 I tried 180 and 165 grain rounds from two different manufacturers, and I couldn't really tell a lick of difference between the two. I had always hear that 180's had less felt recoil.

    Now, there are low recoil 165 grainers made by some manufacturers as practice ammo, and also some old FBI spec 180 @ 950fps that will recoil less than the full power rounds.
