I don't know if the difference in the running speeds is great, but it does seem to be there nonetheless. Mainly because, when Leon is either unarmed, or equipped with an egg or grenade, or with a one-shot RL, he is able to swing his arms to their fullest arc and this seems to make him move marginally faster. On my GC version anyway.
I'm finished with Chapter 4-2, but it was tough. Very tough. Due to one area alone.
The Plaga mines area was negotiated okay. The Dr Salvador you encounter here is a little lazy- he tends to just languish near the boulder unless you move into his direct eyesight, which seems to activate him. So, I retreated to the top part of the area, let the four Ganados that spawn with the Salvador come after me, disposed of them, then activated the Salvador- and used the ladder to knife him to death as he tried to climb up. Took a while, but nice and easy and failsafe. Just a note here, don't try the ladder tactic unless the other Ganados are gone- you don't want to be finishing them off before they jump down the ladder then suddenly have Dr Salvador climb up behind you. It goes without saying, but you'll wind up minus your head!
The Dos Gigantes were easy as always- I just dropped one into the lava and then knifed the other. Took a while and I actually did get hit once, but I was fine apart from that.
And then it was time for the Novistador cave....
On Professional, this is a tough area full stop. Armed with only a Handgun and knife, it becomes very nasty indeed. There are around forty Novistadors in the area, and it is very easy to get trapped and surrounded by them- at which point, armed with only a Handgun, you'll have no chance of survival at all. So my plan was to run equipped with an egg and just try and run past them- stopping and trying to take them on with a Handgun is asking for trouble. However, unfortunately the ones from the bottom of the caves follow Leon up as he moves deeper into the caves, so when I activated the second switch, I was being pursued by around thirty Novistadors! Some of them right on my heels. Not surprisingly, I perished- Leon's face was burnt off rather quickly.
So on my second attempt, I decided to lure the initial wave of 20- one or two at a time- of them into the long passage leading back to the Gigante area, and try and kill them there. And, because that passage is relatively narrow, it's hard to be surrounded by the insects there. It worked. Without those 20, I had a much greater chance. The activation of the first switch was followed by taking out the wave of five that spawn, a fair bit of kicking was involved and I took a hit once, but got out of there. And then for the second switch- which is much more dangerous than the first because the Novistadors that spawn on that occasion are much more agressive and quick- they follow Leon in to the dead-end cave almost instantly. So this time, no way was I taking the chance of taking the swarm on- I just hightailed out of there. Kicked a few out of the way, shot a couple dead when I had a spare moment- and got out of there. It was disappointing to die here once, but I guess I wasn't too surprised. Taking on forty Novistadors on Professional with only a Handgun is no easy task!

Next is 4-3. Normally I find this chapter one of the easier ones in the game, but armed with only a Handgun, it could well transform into something much harder. Taking on up to 75 Ganados (including FOUR Dr Salvadors!) with only a Handgun- well, it could be interesting!
