I've more then once voiced my opinions on one handed shooting. Was gonna stay out of this one but I can't.
ISU (International Shooting Union) is strictly one hand. You have slow fire, which is some weird rap around pistol and you get something like 2.5 hours to shoot 60 rounds (If I remember right, its been a while since I've shot any international). But its ONE HAND.
Then you have Rapid Fire. You have 5 targets similar to the B27 LE Target.
At 25 meters you start with your pistol at 45 degrees, arm extended. When the targets face, you have 7 seconds to engage all five targets. You then have two more stages, the same targets, same range, in 5 seconds and then 3 seconds.
Can't say one handed shooting is slow. Five targets at 25 meters in 3 seconds isn't what I call "SLOW".
My opinion is most, probably 90% of practice for SD should be one handed, most of that with your weak hand.
Think about it, unless you're on the range, getting ready to shoot, how many times during the day do you have both hands free.
You always have something in your hand. Flashlight, money from an ATM, door knob, pushing your wife and kids out of danger, car door, Cell phone to police, etc etc. I could go on forever but you get the idea.
Cover. We all know you want to seek cover when ever possible. Do this little trick. Find a barricade. Get you're partner to get behind the barricade and you stand in front of it. Have your partner point his/her index finger around the barricade as if it was a pistol. Have him/her use one hand, then two.
Notice how much of of body is exposed with two hands compared with one hand.
Now get on the other (left) side of the barricade. Have your partner point his/her finger at you using the right hand, as if he/she was using a two handed grip and again using a one handed grip.
Try the same thing using the left hand on the left side of the barricade, both one and two hands.
See for yourself which method exposes more of your body.
I spent 20 years in LE. I cannot remember one time where I had to draw my service revolver where I had the option of using two hands. I always had something or other in my other hand. We did most of our building searches alone, or maybe if available one other guy. You always had something else in the other hand, flashlight, mirror, door knob.......something.
Same thing as an infantryman in SE Asia. The times I had to use a 1911 was while crawling on my hands and knees or in the mud. Usually with a red lens flash light.
We practice and shoot with two hands because of ego. We shoot better with two hands and refuse to accept the ideal we are poor shots using one hand so we try to justify two handed only shooting.
I'm the same way. I shoot a lot of action style pistol/revolver matches. Like the rest of the shooters I use two hands (except in stages requiring one hand) but that's competition, not SD.
I pocket carry a 642 and do a huge majority of my shooting one handed, the exception being using both hands on a hostage target.
My advise is to swallow your pride, learn to shoot and practice using one hand. Its gonna suck at first, especially using your off hand (left hand for right handed shooter), but eventually you'll gain confidence.
Grip and style varies with the shooter and pistol/revolver involved. I can't tell you what works best for you and your gun with out watching you shoot.
Go to the CMP Bookstore and spend $6.95 on the AMU Service Pistol Guide. It will give you the fundamentals you need in shooting a pistol one handed. Best $6.95 you can spend, Written by the best shooters in the world.

If you set aside your ego, and think about it a bit, you'll see that in self defense situation, the majority of the time you will only have one hand available.
Another book I'd recommend (It was required reading for my rookies when I was an FTO) is Bill Jordon's NO SECOND PLACE WINNER.
Mr Jordon pushed the ideal of doing a lot of practice, drawing and firing one shot, one handed.
