Magnaported so kicks less than both in standard barrel lengths.
Like OysterMan's, mine also wears Crimson trace laser grips.
At short range...ya barely use the sites, at longer range...the CT's are a cool thing
to have...lol
I did see a few years back,
A comparison of the SP101 with both barrel lengths.
Results were....both can be worn and hidden evenly.
Were mine STOCK...think would go for the longer barrel.
The bullet travels SLIGHTLY faster...not enough to matter IMHO, but the added sight distance did add to accuracy with stock guns.
Just my 2 cents.
P.S.
To those that own the snubbie version of the Security SIX...KUDO's.....
Know the SS well.....total envy.....lol
And for those that think the SP101 is heavy......
Drop very little bucks on an UNCLE MIKE'S nylon pancake holster.
Mine holds the gun close, Never even notice the gun there!
