juliet charley - I will address you points in order.
(1) Give more recoil and muzzle flash (both control issues) -
This depends on the load used.
(2) My experience with 10s is they certainly have more muzzle blast than the .45--a definite negative for shooting in enclosed spaces (e.g., one's home) -
Again, this depends on the load used. My experience has been different.
(3) It will give more penetration than just about any .45 ACP round--another negative for home defence. -
Penetration is a product of bullet construction. When choosing a load for home defense this must be considered. However, my 10mm Starfire home defense load doesn't have more penetration than .45acp FMJ, which has been touted as the best defensive load by gun rag whor...er...writers such as Chuck Taylor. Just because he writes that crap doesn't make it true.
(4) It is harder (takes more effort/dedication) to master than most other available weapons (this per Walter Rauch in a Glock Annual about the G20--the full-size version). If I want precision anywhere, I want it my home. -
Just because Walt Rauch can't handle a G20 doesn't mean it can't be done. Have you ever fired a 20 or 29? I own a 20 and it replaced my beloved SIG Sauer P220 .45acp as my home defense gun. It is also my backpacking gun. The P220 is still my carry gun because it is more comfortable to carry. I think both are capable, but for home defense I like the greater power offered by the 10mm. YMMV.
(5) If you visit glocktalk's "Ten Ring" (the 10 mm Forum), some people experience reliability issues with the 29. (I'm just relaying what I read on Glocktalk--take issue with them.) -
Folks on these forums have problems with their .45acp, usually a 1911 of some sort, all the time. Are you suggesting that only 10mm's have this problem? I'll take issue with you on this point because you bring it up without any experience of your own. I haven't had any problems with my 20 or the 29 I borrowed. Some other fellows trouble may have been shooter induced.
(6) The ammo can be difficult to find in local stores. The selection will probably be very limited (e.g., where I live you can only find UMC) and prohibitively expensive in those same local stores. Admittedly, it's not a problem for me--I buy most of ammo mail order and in bulk, but unless, you know what you're getting into and don't mind messing with mail order/bulk buys, the G29 is not "better." -
This can be true of any load. My favorite shop doesn't carry Winchester SXT's. Should I only shoot 9mm because of this? The fact is most shops will oder whatever you want, within reason. This is the case with my favorite shop. Either way, this is a weak point. Some things in life require that you make an effort. This just may be one of them.
All that being said, I am a 10 mm, G20 fan. It is just a long way from being "better" for the uses described. -
That is your opinion, not a fact.
It would have been useful for you to have included some rationale for your statement (unless of course,you were just trying to be funny--then you probably needed a little more than just a smiley)--someone might have actually taken you seriously. -
I have fired a 20, 29 and 30 for a side by side comparison. What I found was that the 20 and 29 both had less felt recoil than the 30. You may feel differently once you get a chance to try for yourself. You're still posting other people's opinions as though they were your own. The 
was used to convey a sense of kidding for making a choice different than mine. If you don't want to take my reply as serious, you don't have to. If you don't like my opinion, take it to e-mail.
