What's wrong here? Model string is NULL.
(I would like to replace the model of monster_satchel next)

#include <amxmodx>
#include <amxmisc>
#include <fakemeta>
#include <hamsandwich>
#include <engine>

#define PLUGIN "Satchels"
#define VERSION "1.0"

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    RegisterHam(Ham_Spawn, "monster_satchel", "fw_SatchelSpawnPre", 0)
}

public fw_SatchelSpawnPre(ent)
{
    if(pev_valid(ent))  
    {
        new s_Model[32]
        pev(ent, pev_model, s_Model, 31)
        client_print(0, print_chat, "SATHCEL MODEL: %s", s_Model)
    }
}

Have you tried search lately? Anggara_nothing's work is a decent place to start.

Entity Spawn is called too early, you better use FM_SetModel post hook

POST. I tested and it works..

#include <amxmodx>
#include <amxmisc>
#include <fakemeta>
#include <hamsandwich>
#include <engine>

#define PLUGIN "Satchels"
#define VERSION "1.0"
#define AUTHOR "Phant"

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    RegisterHam(Ham_Spawn, "monster_satchel", "fw_SatchelSpawnPost", 1)
}

public fw_SatchelSpawnPost(ent)
{
    if(pev_valid(ent))  
    {
        new s_Model[32]
        pev(ent, pev_model, s_Model, 31)
        client_print(0, print_chat, "SATHCEL MODEL: %s", s_Model)
    }
}

PHP Code:

void CSatchelCharge :: Spawn( void )
{
    Precache( );
    // motor
    pev->movetype = MOVETYPE_BOUNCE;
    pev->solid = SOLID_BBOX;

    SET_MODEL(ENT(pev), "models/w_satchel.mdl");
    //UTIL_SetSize(pev, Vector( -16, -16, -4), Vector(16, 16, 32));    // Old box -- size of headcrab monsters/players get blocked by this
    UTIL_SetSize(pev, Vector( -4, -4, -4), Vector(4, 4, 4));    // Uses point-sized, and can be stepped over
    UTIL_SetOrigin( pev, pev->origin );

    SetTouch( &CSatchelCharge::SatchelSlide );
    SetUse( &CSatchelCharge::DetonateUse );
    SetThink( &CSatchelCharge::SatchelThink );
    pev->nextthink = gpGlobals->time + 0.1;

    pev->gravity = 0.5;
    pev->friction = 0.8;

    pev->dmg = gSkillData.plrDmgSatchel;
    // ResetSequenceInfo( );
    pev->sequence = 1;
}
