I like 40 S&W too.
Whether a bit more KE is better than a bit more diameter is debatable.
I have another Glock 35 it still has its 40 S&W barrel and Trijicon HD's - POI matches my POA well with that combo.
The 35 with XS Big Dot POI was a bit high with 40 S&W but is perfect with 357 Sig - I'm picky, we are talking 1.5 inch.
In the Lucky Gunner 357 Sig
(AKA 9mm is best) video you linked he says maybe there is something in shootings that is not seen/reflected by gel and I agree.
I don't think gel reflects the advantage of increased KE and I'll give an example.
In the Lucky Gunner 38/357 mag ammo test:
38 Special 4'' barrel 158 LSWCHP 13.4'' / .56
(298# KE)
357 Mag 4'' barrel 125 SJHP 13.6'' / .54
(602# KE)
357 Mag is hitting with 2x the KE of 38 Special, yet result in gel is about the same.
Do I think the ASAP incapacitation potential of those two is about the same. NO I don't.
In Lucky Gunner test of 10mm the Hornady 155 XTP expands to about .65
I shot a deer with that bullet and measured holes in tissue of 1 1/4 inch.
Damage to tissue was greater than expanded diameter of bullet or what would be expected based on expansion in gel.
Back to 357 Sig vs 40 - if I look at expansion in gel 40 wins.
However, I'm of the opinion that gel may not reflect benefit of increased KE based on the near identical 38/357 Mag gel results and what I documented in tissue.
One of my pics. A quarter is .95 and that hole is bigger - from a bullet that expands to about .65
The deer was shot with a 10mm Colt Delta Elite.
Just so happens that with my Glock 20SF POI matches my POA perfectly with Hornady 155 XTP and the Glock 20SF is concealable for me AIWB

357 Sig and 10mm - for those that think increased KE may be beneficial.
