Wrist Angle

I had one of my best days at the indoor range trying to finish lesson two which is getting all 10 shots is a plain black center twice in a row.  I fired ten dry fires as susjected by amother member as my first target normally sucks.  Shooting the first 10 shot string I went 8 for 10 but discovered if I lock my wrist down so the back of my thumb is a stright line over my wrist and up my arm I stayed on target better.  The second 10 was 10 in the black now just need one more.  Dang 9 of 10 with one a 1/4" out.  Is this wrist position correct or am I now doing something incorrect that I will need to correct later?  Don

To shoot good scores you want a small group......  I can tell you what I do to get a good group but that is for me.  You need to find what it takes for you.  Try different things and write it down so you have notes on what your doing.  What produces the best groups. For slow, timed and rapid. 
 I think it all starts at the feet.  I like to stand at a 45 deg. from the line because of back issues.  But then I have to force things to line up which I think is not the best way.  Just my 2 cents.....

If you can find a copy on the internet, a gold mine of wonderful information can be found in "The Pistol Shooter's Treasury".  I read it two years ago, and as was suggested in this forum, started reading it again because of some issues I've been having.

This time, I read it with my gun right alongside the book.  When I tried to do things as described in the book, I found several things I have been doing wrong.  

The single biggest thing you can do to improve your groups (at least for me) has been dry fire, many, many times.  And as you wrote, when you get to the range, dry fire there until you're feeling comfortable, and then start on live rounds.

I have found more than once that if I change something, particularly if accidentally, or on a whim, I might shoot better that day, but then the next time it doesn't work as well. Had the same experience when I used to golf. Perhaps see how it works the next few times?

Maybe you just need some euro guns

Like Greg said above, it worked that day and didn't feel right the next day nor did it work.  Lately I been going to the indoor range and shooting guns out of the safe I have not shot in a long time.  Two handed.  Shot my M&P 22 FS last.  Shot it a lot better then before I put it in the safe a year ago.  This BE shooting has helped a lot.  Also shooting it showed me how much better my Nelson is.  Don
