OTOH, with my Ruger Alaskan, a switch to the GP100 compact grips has allowed me to fire 50 rounds one-handed from a 44 Mag snubbie & do just fine.
Freakin'-A correct! That huge magazine for those 15 rounds is also compromised by the looooonng trigger pull, which is supposed to enhance safety. Anybody remember the scene from Black Hawk Down where the Delta operator was chewed out by the Ranger Captain for having a "hot" weapon inside the cantonment area? The Delta guy showed his trigger finger and said This is my safety, sir! Well that is spot on correct. Ladies with smaller hands have to sometimes shift their grip on the M9 to get enough strength in the trigger finger to pull the trigger. What pray tell happens when one shifts his grip on the weapon in this fashion? If you answered the point of impact also shifts you're sadly correct.
When I first met the gal who became my wife exactly 23 years ago last month, our first date was to church and the second date was to the range. She had already handled firearms in her past (being the daughter of a combat decorated WWII USMC Colonel) so I broke her in on my customized 1911 Remington Rand, affectionately known as Betsy. She did very well but waited wisely until the nuptials were over before declaring my beloved Betsy, HERS. To keep the peace I had to immediately buy her a 1911 45 Combat Commander and it's been wedded bliss ever since.
