I already own a 9mmSC. I've decided to purchase another XD, but I just can't decide if I should go with the 9mm v-10 (should kick something like a .22).
Or the Tactical in 9mm just because it should be a bit more accurate to shoot. Both of these reasons sounds good for range day, so i'm completely torn between the two.
If you are looking for an accurate range gun that has the recoil of a .22, why not consider actually getting a .22?
I have the XD9 Subcompact just like you. And a 1911 in .45 caliber.
I recently got a Ruger target .22 - it cost me less than any XD. I could have spent more on a new stainless Ruger than I did on a used blued one, and still have spent less than what a new XD would have cost.
The Ruger is a TON of fun to shoot. It is amazingly accurate. At 30 feet I can almost always put every shot in a dime sized group (my eyesight could be better....so I got a red dot scope, which lets me shoot at 50 or 60 feet for more of a challenge).
The cost of ammo at Walmart....cheapest "value pack" stuff----
9mm costs about ten cents per bullet. The .45 caliber (not always available) is twenty cents a bullet. The .22 caliber rounds cost two cents a piece. It really is nice to shoot a hundred rounds for $2 instead of for $20 in .45 caliber and $11 for 9mm. (or substantially more if you pay gun store prices rather than Walmart prices).
I love shooting all the guns. I think the SC is amazingly accurate at defensive distances. The .45 is (for me) still a challenge to learn to shoot well, but it is a lot of fun to shoot. And is a very accurate gun in the right hands with it's 6 inch barrel as opposed to the 5 inch Tactical XD, and a famously accurate round...The ACP..big, heavy and slow. But it's very expensive to shoot.
I can't say I like any one of the three guns more or less than the others. They each have their own special "charm".
But I can say I have gotten the most "bang for the buck" with the Ruger.
It sounds like you are in a similar situation to mine when I bought the Ruger. You want a range gun. You want accurate. Everyone likes to shoot a lot, so I will assume you would rather spend $2 to shoot a hundred rounds than $10 or $20 (at least).
You obviously are not looking for a carry gun, or you would not have mentioned the ported or the Tactical. (And you are covered for carry with the SC already).
Everyone mentions how much cleaning the ported gun requires. The porting serves to reduce recoil (which really does help accuracy).....The .22s have virtually no recoil in a heavy target pistol and they seem to like being "dirty".....at least that seems to be the consensus of owners.
You can't go wrong with any choice though. All great guns. The XD Sub amazes me every time I shoot it. How can such a small gun be so accurate? And have so little recoil?? A truly super designed and well made gun.
Good luck with whatever you decide.
