Chris, pardon me for jumping in?  I'm sure Jerry will happily comment as well, but since I have both the G24 and G35 myself I'll add to whatever Jerry tells you.  Both are accurate, and the G35 really has a stellar reputation.  As an accurate plinker you won't go wrong with either. 

The only real difference is the 5.3" barrel vs the 6" barrel, as the balance is ever so slightly different--and I mean slightly.  The triggers and sights are the same.  G35s are usually slightly less money than the 24, and are far more available as the 24 isn't made as often.

The G24, however, can be had compensated* or not.  (*I use Glock's term "compensated" but you should know there is no expansion chamber at the muzzle, part of the definition of "compensated."  Rather the Glocks are simply "ported," with slots being cut through the barrel via electro-discharge machining.) 

The ones that are compensated (or ported) do have less recoil, but if you are a seasoned shooter both are quite easy to handle, ports or not.  I suspect a professional sport shooter could show a difference in speed shooting between a ported and non-ported version of the same model Glock, but I'm not sure I could.

As to the porting on the G24, it has slots on the top of the barrel angled to eject combustion gasses directly into the rear portion of the front sight.  Other "C" model Glocks have porting on the upper sides and vent gas at an angle to either side of the pistol, so this problem only exists with the so-called "international target" models, the G17L and G24C. 

What I took to doing when shooting GSSF was putting some Hoppe's #9 powder solvent on a Q-tip and rubbing the front sight of my G24C clean in between strings of fire or at least in between matches.  The white on the Glock sights is not paint, it is plastic molded through and through, so solvents that are safe for the rest of the sight, or the whole frame, are safe for the white dot.

That said, there are two fixes, neither terribly expensive.  First is to get a non-ported barrel for the G24.  Glock barrels are around $130 and aftermarket brands are both lower and higher in price.  Glock barrels will drop right in with no fitting required, most aftermarket barrels will drop in as well although there are no guarantees.  This will negate the recoil reducing aspects of the ported models but will solve the sight fouling problem.

Alternative two is to replace the sights with all-black sights that don't mind fouling as you are sighting via a dark outline only, not looking for a bright highlight.  This may cost as much as a$100 but more likely would be closer to $50.

Actually there is a third alternative--ignore the fouling and use the sight outline rather than the white dot.  If you have under-40-year-old healthy eyes this is easily do-able.  I'm 52 and I don't see as well, especially on an indoor range, so I really appreciate the bright white highlights of Glock factory sights.
